tical to use a single rope with a high factor of safety. Even
so, when the car is at the bottom, there is approximately
160 m of rope deployed. To prevent the cab level from
creeping up or down as passengers enter or exit, an ac-
tive control system is used to keep the car aligned with
the deck level. A closed-loop control system is used on
the motor inverter so subtle changes in motor/winch
drum position are possible while the car is being loaded.
Communication between the car and main control sys-
tem is via a failsafe radio link.

generate the laser cutting files for the prefabricated rail-
transition sections. Next, the rail structure was manufac-
tured in New Zealand as a kit set that could be broken
down to 5-m-long modules for sea freighting to Vietnam.
These rail modules were bolted together on site over an
eight-week construction period.
Range of Involvement
Access Automation was closely involved with various
aspects of the elevator project over a limited timeframe. It
made the initial site visit and worked with the client’s ar-
chitect and engineer to develop the project layout and
specification that met the resort’s needs. In addition, it
provided rail and foundation structural designs, R&D and
construction design of the mechanical parts, manufac-
tured all electrical and mechanical elevator components,
and installed and commissioned the equipment.
In many ways, the most interesting challenge of the
project was turning the architect’s vision of the Vietnam-
ese fishing boat into a safe and functional elevator cab.
The dilemma was for the exterior of the car to have a rus-
tic, hand-finished appearance, while not compromising
passenger comfort or safety. The cars were fabricated in
New Zealand using stainless-steel frames that form the
boat shape. The car interiors are clad with embossed
stainless-steel panels and feature modern controls and
safety features. The connection between the boat and the
supporting chassis below is via rubber pads to act as a
final step to maintain ride smoothness.
Due to the complexity of the rope-management system
around the various sheaves and bends, it was more prac-
